The dynamic regulation of a power supply is improved by increasing the value of:

  1. A the bleeder resistor
  2. B the output capacitor
  3. C the choke
  4. D the input capacitor

Correct answer: B — the output capacitor. From the official ISED question bank, verified word for word.

Why

Increasing the output capacitor acts like adding a larger water tank to smooth out sudden changes in demand, allowing the power supply to react faster when the load shifts. The full explanation — and one for every question — is in Pro.
